2. OBJECTIVES Review basic configuration of EIGRP on a serial interface
Configure the bandwidth-percent command
Configure EIGRP over Frame Relay hub and spoke
Use EIGRP in non-broadcast mode
Enable EIGRP manual summarization in topologies with discontiguous major networks

3. TOPOLOGY
NOTE:-
Given the diversity of router models and the differing naming conventions for serial interfaces (S0, S0/0, S0/0/0),
The interface numbers on devices will probably differ from those in the topology diagram.

4. Contd.. Always draw network diagram to reflect topology.
If any uncertainty for DCE connection, then use the show controllers serial interface_type interface_number command:
HQ# show controllers serial0/0/0
Interface Serial0/0/0
Hardware is GT96K
DCE V.35, clock rate
<output omitted>

5. scenario
Suppose a company want to a new network between company Headquarter(HQ) , East, and west branches.
They are connected over hub and spoke Frame relay. company headquarter use as Hub.
Each network with multiple loopback interfaces on each router.
EIGRP to allow full connectivity between all departments.
To simulate the Frame Relay WAN connections.
Use a router with three serial ports configured as a frame switch.
Note:- router configuration is described in Step 2.

6. STEP 1: ADDRESSING
Apply IP addresses to the loopback interfaces on HQ, East, and West.
Paste the following configurations into routers to begin must be in configuration mode when do this.
HQ: !
interface Loopback1
ip address
interface Loopback33
ip address
interface Loopback65
ip address
interface Loopback97
ip address
interface Loopback129
ip address
interface Loopback161
ip address
end

7. Contd.. NOTE: all code is same just replace the only 1,
In each address. (HQ=1, East=2, West=3).
As Like: East:- ip address
West:- ip address
For now, the IP address is the only configuration on the serial interfaces.
Leave the serial interfaces with their default encapsulation (HDLC)

8. Configurations
Recommendations are described in terms of configuring the interface "bandwidth" parameter
EIGRP being able to use 50 percent of that bandwidth by default.
Bandwidth configuration cannot be changed
Bandwidth-percent command should be used to control the EIGRP bandwidth
On low-speed interfaces, raising the available bandwidth for EIGRP above the default of 50 percent is advisable in order to improve convergence.

9. Contd.. LAN Interfaces (Ethernet, Token Ring, FDDI)
set by default to the actual media speed
bandwidth is explicitly configured to a very low value. Then need to configure.
Point-to-Point Serial Interfaces (HDLC, PPP)
defaults to T1 speed (1.544 Mbps) on serial interfaces
set to the actual link speed.
NBMA Interfaces (Frame Relay, X.25, ATM)
particularly critical to configure nonbroadcast multi-access (NBMA) interfaces correctly.
otherwise many EIGRP packets may be lost in the switched network.

10. Contd.. Three basic rules
The traffic that EIGRP is allowed to send on a single virtual circuit (VC) cannot exceed the capacity of that VC.
The total EIGRP traffic for all virtual circuits cannot exceed the access line speed of the interface.
The bandwidth allowed for EIGRP on each virtual circuit must be the same in each direction
Three different scenarios for NBMA interfaces
Pure Multipoint Configuration (no subinterfaces)
Pure Point-to-Point Configuration (each VC on a separate subinterface)
Hybrid Configuration (point-to-point and multipoint subinterfaces

11. PURE MULTIPOINT CONFIGURATION (NO SUBINTERFACES)
EIGRP will divide the configured bandwidth evenly across each virtual circuit.
Must ensure that this will not overload each virtual circuit.
For example:
if you have a T1 access line with four 56K VCs, you should configure the bandwidth to be 224Kbps (4 * 56Kbps) in order to avoid dropping packets. If the total bandwidth of the virtual circuits equals or exceeds the access line speed, configure the bandwidth to equal the access line speed. Note that if the virtual circuits are of different capacities, the bandwidth must be set to take into account the lowest capacity virtual circuit.
For instance, if a T1 access line has three 256Kbps VCs and one 56Kbps VC, the bandwidth should be set to 224Kbps (4 * 56Kbps). In such configurations, putting at least the slow virtual circuit onto a point-to-point subinterface is strongly recommended

12. PURE POINT-TO-POINT CONFIGURATION (EACH VC ON A SEPARATE SUBINTERFACE)
configuration allows maximum bandwidth control, since the bandwidth can be configured separately on each subinterface
virtual circuits have different capacities. It is best configuration.
total bandwidth for all subinterfaces cannot exceed the available access line bandwidth
If the interface is oversubscribed, the access line bandwidth must be divided across each of the subinterfaces
For Example:-
if a T1 access line (1544 Kbps) has ten virtual circuits with a capacity of 256Kbps, the bandwidth on each subinterface should be configured to be 154Kbps (1544/10) instead of 256Kbps each.

13. HYBRID CONFIGURATION (POINT-TO-POINT AND MULTIPOINT SUBINTERFACES)
combinations of the two individual strategies
Examples :
To set the interface bandwidth to reflect the PVC capacity,
Adjust the bandwidth prcentage for EIGRP.
example, the desired
bandwidth for EIGRP is
(256K/10)*.9 = 23.04K;
the bandwidth percentage would be 23.04K/56K = .41 (41%).
So the same effect would be
had by configuring:
Interface Serial 0.1 point-to-point
bandwidth 56
ip bandwidth-percent eigrp
Dotted Line :- corresponds to separate PVC
Color: a separate IP subnet

14. Configuration Hub Router interface Serial 0 encapsulation frame-relay

ip bandwidth-percent eigrp
!--- To configure the percentage of bandwidth that may be
!--- used by EIGRP on this interface.
interface Serial 0.2
point-to-point bandwidth 25
Each of the ten spoke routers must be configured to limit EIGRP traffic to the same rate as that of the hub, in order to satisfy the third rule

15. Contd..
Spoke Router interface Serial 0 encapsulation frame-relay !--- To enable Frame Relay encapsulation on this interface. interface Serial 0.1 point-to-point !--- The subinterface is configured to function as a point-to-point link !--- using this command. bandwidth 25 !--- To set the bandwidth value for this interface. ip bandwidth-percent eigrp !--- To configure the percentage of bandwidth that may be !--- used by EIGRP on this interface.

16. FULL-MESH FRAME RELAY CONFIGURATION WITH DIFFERING ACCESS LINE SPEEDS
A fully-meshed Frame Relay network of four routers running IPX EIGRP process ID 456, configured as a multipoint network
Note:-
Three of the four routers (routers A through C) have 256Kbps access lines, but one (router D) has only a 56Kbps access line. In this scenario, the configuration must restrict EIGRP's bandwidth in order to not overload the connection to router D. The simplest approach is to set the bandwidth to 56Kbps on all four routers.

17. Contd..
Routers A-D interface Serial 0 encapsulation frame-relay !--- To enable Frame Relay encapsulation on this interface. bandwidth 56 !--- To set the bandwidth value for this interface

18. a point-to-point subinterface
Note:-
EIGRP will divide the bandwidth evenly across the three PVCs. Note, however, that this is overly restrictive for the PVCs connecting routers A through C, since they have sufficient capacity to handle a lot more traffic. One way of handling this situation is to convert the network to use point-to-point subinterfaces for all PVCs, as in the example above. Another way, which would require less configuration, is to break up the network by putting routers A through C on a fully meshed multipoint subinterface, and use a point-to-point subinterface for connecting to router D, and making all of router D's connections point-to-point subinterfaces instead

Notes:-
multipoint subinterface is configured to 238 Kbps (256-18) and the point-to-point subinterfaces are configured to 18 Kbps (56/3).

22. STEP 2: CONFIGURING THE FRAME RELAY SWITCH
Use 4th Cisco router with 3 serial interfaces.(as a frame relay switch and cable the routers) .
Paste the following configuration into the router (depending on which equipment you have, the interface numbers may be different). !
hostname FRS
frame-relay switching
interface Serial0/0/0
description FR to HQ
encapsulation frame-relay
clock rate
frame-relay lmi-type cisco
frame-relay intf-type dce

23. frame-relay route 102 interface Serial0/0/1 201

interface Serial0/0/1
description FR to East
no ip address
encapsulation frame-relay
clock rate 64000
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 201 interface Serial0/0/0 102

24. CONTD… interface Serial0/1/0 description FR to West no ip address
encapsulation frame-relay
clock rate 64000
frame-relay lmi-type cisco
frame-relay intf-type dce
frame-relay route 301 interface Serial0/0/0 103
no shutdown
! End

25. STEP 3: CONFIGURING THE FRAME RELAY ENDPOINTS
Frame Relay(HQ), Spokes (East and West).
Check the topology diagram for the data-link connection identifiers (DLCIs).
Off Turn Frame Relay Inverse Address Resolution Protocol (InARP).
Configure all Frame Relay interfaces as physical interfaces.
Inverse ARP allows a Frame Relay network to discover the IP address associated with the virtual circuit
A desirable trait in a production network.
Turn Inverse ARP off to limit the number of dynamic DLCIs that are created.

26. CONTD… Its work in these pahses;-
For a global configuration mode enter the configuration menu for that assign it an IP address with the help of ip address command.
fourth octet of the IP address is the router number (HQ=1, East=2, West=3
Assign the Frame Relay subnet to be /29.
Enable Frame Relay encapsulation using the interface configuration command encapsulation frame-relay.
Disable Frame Relay Inverse ARP with the no frame-relay inverse-arp command.
Notes:
The broadcast keyword is important because, without it, EIGRP hello packets are not sent through the Frame Relay cloud. Do not forget to bring up your interfaces with the no shutdown command

27. CONTD….
Map the other IPs in the subnet to DLCIs, using the frame-relay map ip address dlci broadcast command
HQ# conf t
HQ(config)# interface serial 0/0/1
HQ(config-if)# ip address
HQ(config-if)# encapsulation frame-relay
HQ(config-if)# no frame-relay inverse-arp
East# conf t
East(config)# interface serial 0/0/1
East(config-if)# ip address East(config-if)# encapsulation frame-relay
East(config-if)# no frame-relay inverse-arp

28. Contd.. East(config-if)# frame-relay map ip 172.16.124.1 201 broadcast
East(config-if)# no shutdown
West# conft
West(config)# interface serial 0/0/0
West(config-if)# ip address
West(config-if)# no frame-relay inverse-arp
West(config-if)# encapsulation frame-relay
West(config-if)# frame-relay map ip broadcast
West(config-if)# frame-relay map ip broadcast
West(config-if)# clock rate 64000
West(config-if)# no shutdown

29. Contd..
Each frame relay end points check the connectivity across the frame Relay network by the pinging the remote routers.
For more information about this behavior of Frame Relay, see the following FAQ page:

30. STEP 4: SETTING INTERFACE-LEVEL BANDWIDTH
Set the Frame Relay serial interface bandwidth with the interface-level command bandwidth bandwidth, specifying the bandwidth in kilobits per second. For HQ, use 128 kbps. On East and West, use 64 kbps
by default, EIGRP limits its bandwidth usage to 50 percent of the value specified by the bandwidth parameter.
Each neighbor for which this is an outbound interface has a traffic limit of a fraction of that 50 percent, represented by 1/N, where N is the number of neighbors out that interface
HQ(config)# interface serial 0/0/1
HQ(config-if)# bandwidth 128
East(config)# interface serial 0/0/1
East(config-if)# bandwidth 64
West(config)# interface serial 0/0/0
West(config-if)# bandwidth 64
Notes:- The default bandwidth for a serial interface is 1544 kbps. .

31. CONTD…
How much bandwidth on Serial 0/0/1 on HQ is reserved for EIGRP traffic to East?
On HQ, up to 32 Kbps of bandwidth can be utilized for EIGRP traffic to East. This represents one fourth of the total bandwidth of that interface
Control both the bandwidth parameter and the EIGRP bandwidth percentage on a per-interface
On HQ, limit the bandwidth used by EIGRP to 40 percent without changing the bandwidth parameter on the interface.
The interface-level command ip bandwidth-percent eigrp as_number percent:
HQ(config-if)# ip bandwidth-percent eigrp 1 40

32. STEP 5: CONFIGURING EIGRP
Use the global configuration mode command router eigrp as_number
Represented discontiguous network ( /8) configured on all routers.
HQ sends and receives summaries for /8 from both East and West
Auto summarization provokes considerable routing disruptions in the network and turn off auto-summarization on each router.
two major networks using here are network for the loopbacks, and network for the Frame Relay cloud.
Perform this configuration on all three routers
HQ(config)# router eigrp 1
HQ(config-router)# network

33. Contd.. HQ(config-router)# network 172.16.0.0
HQ(config-router)# no auto-summary Same for East and West
Issue the show ip eigrp topology command on East:
East# show ip eigrp topology

East#
Which networks are missing from the topology database?
All of the subnets in the /16 range are missing from East’s topology table. These are the remote loopback interfaces on the West router.
What do you suspect as being responsible for this problem?
This problem is caused by the split horizon functionality on R1. R1 will not send route updates from East to West because the incoming interface and outgoing interface are the same.

36. Contd..
Router 1 needs the no ip split-horizon eigrp as_number command on its serial Frame Relay interface
This command disables split horizon for an EIGRP autonomous system
If split horizon is enabled (the default), route advertisements from East to HQ do not travel to West and vice versa,
Example :
HQ(config)# interface serial 0/0/1
HQ(config-if)# no ip split-horizon eigrp 1

37. Contd..
Verify the correct EIGRP adjacencies with the show ip eigrp neighbors command:

Same as another Two (EAST and WEST) ip route.

40. TCL Scripts
Run the following TCL script on all routers to verify full connectivity:
for each address {
(… continue)

41. Contd..
} { ping $address }
If anybody never used TCL scripts or need a refresher, see the TCL lab in the routing module.

42. STEP 6: USING NON-BROADCAST EIGRP MODE
EIGRP use as default mode, which multicasts packets to the link-local address
All Frame relay not support mulitcast.
EIGRP supports unicasts to remote destinations using non broadcast mode on a per-interface basis
mode is analogous to configuring RIPv2 with a passive interface and statically configuring neighbors out that interface
To implement this functionality, do the following:
HQ(config)# router eigrp 1
HQ(config-router)# neighbor serial 0/0/1
HQ(config-router)# neighbor serial 0/0/1
East(config)# router eigrp 1
East(config-router)# neighbor serial 0/0/1
West(config)# router eigrp 1
West(config-router)# neighbor serial 0/0/0

43. CONTD… H Address Interface Hold Uptime SRTT RTO Q Seq
HQ now has two neighbor statements, and the other two routers have one. Once you configure neighbor statements for a given interface, EIGRP automatically stops multicasting packets out that interface and starts unicasting packets instead. verify that all your changes have worked with the
show ip eigrp neighbors command:
HQ# show ip eigrp neighbors
IP-EIGRP neighbors for process 1
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num

West# show ip eigrp neighbors

45. STEP 7: IMPLEMENTING EIGRP MANUAL SUMMARIZATION
Implement EIGRP manual summarization on each of the routers.
Each router should advertise only one network summarization.
What is the length of the network mask that is used to summarize all the loopbacks on each router?
Summarize all the loopbacks at the 24-bit boundary for each router.
Simplified EIGRP topology table on each router using the show ip eigrp topology command:
